It's hard to say if Toyota's engineers skimped over a key piece of the development process with this particular example and I'm certain there's no way an engineering team can be expected to anticipate every possible failure given the practicalities and constraints of development cycles. That said, this example points up the very key requirement to do some level of design for misuse as part of the iterative process. It's one of those areas like design for assembly and disassembly that likely gets short shrift in a lot of companies and across myriad industries--not just automotive.
With a better understanding of materials’ response to load and temperature, researchers could potentially use the knowledge to improve design. The research could even help geologists studying plate tectonics.
